Your transactional emails, hosted in France
An open-source email sending platform, an alternative to Resend and SendGrid, installed and maintained by DINAO. API, analytics, and contact management — your campaigns remain sovereign and hosted in France.
What is useSend?
useSend is an open-source email sending platform for transactional and marketing messages, positioned as an alternative to Resend, SendGrid, or Postmark. It wraps email sending in a user-friendly dashboard, API, analytics, contact management, and subscription/unsubscription handling.
It allows you to track your sends, deliverability, and contact engagement in real time, all from a clear interface. On the integration side, its API connects easily to your applications, like a standard transactional service, with domain authentication (DKIM, SPF) to optimize deliverability.
In the self-hosted version at DINAO, useSend runs on your own infrastructure in France: your contacts, templates, and statistics remain sovereign and GDPR compliant, without dependence on a non-EU SaaS service. You retain control over your email channel, with controlled hosting costs.
